Q1: What is the primary application area for Savinyl Brown GLS Pigment?
A: Savinyl Brown GLS Pigment is specifically developed for coloration of polyolefin-based packaging materials, including flexible films and rigid containers intended for food contact applications where regulatory compliance and thermal stability are critical.
Q2: Is Savinyl Brown GLS suitable for high-temperature processing such as injection molding or blow molding?
A: Yes — it is engineered for excellent thermal stability and dispersion performance in polyolefins processed at elevated temperatures, maintaining consistent color strength and minimal volatile generation during extrusion and molding operations.
Q3: How does Savinyl Brown GLS differ from conventional organic brown pigments in polyolefin applications?
A: It offers superior migration resistance and reduced plate-out tendency compared to many standard organic browns, along with enhanced compatibility with common polyolefin additives such as antioxidants and UV stabilizers.
Q4: What is the typical dosage range when using Savinyl Brown GLS in polypropylene or polyethylene formulations?
A: Dosage depends on the desired shade intensity and substrate thickness, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — with optimal results achieved through lab-scale dispersion trials and rheological evaluation.
